1 Kings 6:5-8

5And against the wall of the house he built floors round about, [against] the walls of the house, round about the temple and the oracle; and he made side-chambers round about.

6The lowest floor was five cubits broad, and the middle one was six cubits broad, and the third was seven cubits broad; for in the [thickness of the wall of] the house he made resets round about outside, that nothing should be fastened in the walls of the house.

7And the house, when it was being built, was built of stone entirely made ready before it was brought thither; so that there was neither hammer nor axe nor any tool of iron heard in the house while it was being built.

8The entrance to the side-chambers of the middle [floor] was in the right side of the house; and they went up by winding stairs into the middle [floor], and out of the middle into the third.
